On a coordinate plane, 2 lines with negative slopes are shown. Line M N goes through points (negative 2, 0) and (negative 6, 8).
Line M prime N prime goes through (6, negative 4) and (2, 4). Use the graph of the lines to determine if the two lines are parallel. Line MN was translated down units and right units to create line M'N'.
The slope of Line M N .
The slope of Line M prime N prime .
The first digit of a number can be 1-9. The 2nd and the 3rd digit can be 1-10. The last digit can be 0 or 5 ( 2 numbers ): 9 * 10 * 10 * 2 = 1,800 She could pick 1,800 different 4-digit numbers.
